By 'not looking so good' i ment that they've lost lost alot of weight, but i think you've hit the nail on the head by what you have said. They are kenneled outside and they are being worked less, but their out every morning and night to have a run over the dunes and the beach to try and keep them fit.
I just put up this thread as this is my first summer with them really because last year they were only pups, and was just concerned about them losing their appitite.
Thanks very much for the advice you put my mind to rest , always better to ask if your unsure i suppose.
P.S any advic
